机器人编程:主叫电话号码,并返回被拒绝后,合适的应用程序
问题描述:
我想编写使用eclipse女巫的Android应用程序从用户获取的电话号码,并拨打的电话号码(使用意图或别的东西)后返回该应用程序并调用因响应不同的方法(拒绝,错过了,...)机器人编程:主叫电话号码,并返回被拒绝后,合适的应用程序
我知道如何拨打电话使用意图,但不知道如何处理这种溶液(返回到App权遭到拒绝后或错过)

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
public class PhoneCall {
public static final String PARAM_CALL_DONE = "CALL_DONE";
public static void call(String phoneNumber, Activity activity) {
CallEndedListener.createListenerFor(activity);
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber));
activity.startActivity(callIntent);
}
private static class CallEndedListener extends PhoneStateListener {
private boolean called = false;
private final TelephonyManager telephonyManager;
private final Context context;
private Activity activity;
private CallEndedListener(Activity act) {
this.context = act.getBaseContext();
this.activity = act;
this.telephonyManager = (TelephonyManager) context
.getSystemService(Activity.TELEPHONY_SERVICE);
}
public static void createListenerFor(Activity act) {
CallEndedListener listener = new CallEndedListener(act);
listener.telephonyManager.listen(listener, LISTEN_CALL_STATE);
}
@Override
public void onCallStateChanged(int state, String incomingNumber) {
if (called && state == TelephonyManager.CALL_STATE_IDLE) {
called = false;
telephonyManager.listen(this, PhoneStateListener.LISTEN_NONE);
try {
Intent t = new Intent(context, activity.getClass());
t.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
t.putExtras(activity.getIntent());
t.putExtra(PARAM_CALL_DONE, true);
t.setAction(Intent.ACTION_MAIN);
activity.finish();
activity = null;
context.startActivity(t);
} catch (Exception e) {
e.printStackTrace();
}
} else {
if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
called = true;
}
}
}
}
}
通过交接参数“PARAM_CALL_DONE”,调用活动可以测试它是否被启动/恢复打完电话后。这是有道理的的onResume()来测试它 - 方法是这样的:
@Override
protected void onResume() {
if (extras.getBoolean(PhoneCall.PARAM_CALL_DONE)) {
showInfoText(); // do whatever you like here...
extras.remove(PhoneCall.PARAM_CALL_DONE);
}
}
不要忘记添加的权限清单文件。
<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>
<uses-permission android:name="android.permission.CALL_PRIVILEGED"></uses-permission>
为了使用手机,一个非常简单的方法调用应该是足够的,以“PHONENUMBER”是一个电话号码作为字符串,并从活动
PhoneCall.call(phonenumber, this);
